UM-1 and UM-5 Crystals
O
General specification for 'UM' family crystals
Frequency range 1.0MHz to 200MHz
High-precision crystal ideal for telecoms applications
High quality resistance weld sealing
Suitable for reflow soldering
DESCRIPTION
OUTLINE & DIMENSIONS
UM-1 and UM-5 crystals are a long-established design, being widely
used in telecommunications applications where their compact size
and ease of producing to close tolerances makes them an ideal
crystal. In addition to the standard packages a 'Slimline' package is
also available.
